What would be worth cutting with something that expensive?

okay, top ten.

10. Bill Gates's typing fingers.
9.  The backstreet boys noses.
8.  Mariah Carey's jugular.
7. The wax seal on a bottle of Macallan Scotch ($50-$2500/glass)
6. The end of a Cuban cigar.
5. The foil on a bottle of Krystal champagne.
4.  The brake lines of your (soon to be) deceased wife's 58 Rolls Royce.
3. Your wealthy mother-in-law's oxygen tube.
2. Your son's driver's license after speeding ticket #4 or accident #3.

And the number one thing that that would be worth the use of that knife:

1. Cutting Elizabeth Hurley free from that constricting thong.
